# Conceal

Simple OpenSSL-based string encryption using a shared secret. The algorithm, initialization vector, salt, crypttext, and HMAC are all encoded into a single string
so it is easy to copy around.

## Requirements

* Ruby 1.9.3 or newer

## Installation

Add this line to your application's Gemfile:

    gem 'conceal'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install conceal

## Usage

```ruby
encrypted = Conceal.encrypt('some plaintext', key: 'your shared secret', algorithm: 'aes-256-cbc')
decrypted = Conceal.decrypt(encrypted, key: 'your shared secret')
```
